Ignition Coil - Coil On Plug
WARNING: This page is about a different car, the 2003 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
The engine uses eight separate coil per plug units. Each coil per plug unit is controlled by the powertrain control module (PCM).
Each coil per plug unit is mounted directly above each spark plug and activates its own spark plug in the correct sequence as controlled by the PCM.
Refer to the SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article for additional information on the ignition system.
